life science Maturity 11-13 Next article →

The straw mushroom is a very popular food. People call it *Volvariella volvacea*. It is also known as the paddy straw mushroom. Many people in East and Southeast Asia grow them. They are the third most eaten mushroom in the whole world.

You can find them fresh in some places. In other areas, people eat them dried or in cans. These mushrooms are important to many different meals.

Growing these mushrooms is a quick process. Farmers grow them on beds made of rice straw. They do best in warm, subtropical climates. These areas need a lot of rain each year. The mushrooms grow very fast in these spots. They only take four to five days to mature.

Most people pick them when they are still small. This is called the button or egg phase. They pick them before the veil ruptures.

People have used these mushrooms for a long time. There is no record of growing them before the 19th century.

They are even used to make special sauces. Workers make dark soy sauce by using a broth. They mix the mushroom broth into the sauce. Then, they let the sauce sit in the sun. This makes a dark soy sauce called *cǎogū lǎochōu*. This sauce has a much richer flavor.

It is vital to know how to spot them. Some poisonous mushrooms look almost the same. These are called death caps.

You can tell them apart by their spore print. A spore print is the mark left by tiny seeds. Straw mushrooms leave a pink print. Death caps leave a white print instead. People in California and Australia have been poisoned by mistake. They mixed up the two kinds of mushrooms.

One cup of these mushrooms is very healthy. They provide a lot of food energy.

They have 6.97 grams of protein in one cup. They also have 4.5 grams of fiber. You can find iron and zinc in them too. They have 2.6 milligrams of iron. They also have 1.22 milligrams of zinc. They have many vitamins like B5 and B9. This makes them a very dense food for your body.
